Depending on what PART of the application you want to automate, maybe...

It will probably NOT work on the map itself because it is a 3D rendering inside viewer, which Ranorex will have problems with. Ranorex is designed to automate traditional UI elements, not rendered views, like Google Maps or 3D games, etc.

If you just need to manipulate buttons and such, then probably, but that also depends on how/if Google implemented MSAA correctly/at-all in the interface.
